When you model a product in Pickler, each material needs to be mapped to the best matching dataset in IDEMAT.
IDEMAT works with representative environmental datasets for common material categories and production systems, rather than every commercial material name on the market.
This can sometimes make mapping difficult. In reality, there are thousands of:
supplier-specific material names;
commercial blends;
coatings;
recycled combinations;
and bio-based materials.
Most of these materials do not exist as a 1-on-1 match in IDEMAT.
Instead, the goal is to find the dataset that best represents:
what the material is made of;
how it is produced;
and its environmental characteristics.
In this guide, you will find best practices and practical tips to help you map materials more consistently and better understand the logic behind professional LCA modeling.
Best practices on how to find the right IDEMAT material
You did a search in Pickler and couldn't find a match, try the steps below:
Step 1: Ask Pickler AI
Start by asking Pickler AI which IDEMAT material is the best match.
Pickler AI can:
search IDEMAT;
recognize many common commercial material names;
and suggest suitable proxies.
This is usually the fastest way to find the correct material.
Example questions:
“What is the best IDEMAT match for E-Tissue?”
“What should I map Sugarcane PE to?”
You can also upload:
PDF datasheets;
technical specifications;
EPDs;
or supplier documentation;
to help the AI provide better mapping suggestions.
However, it is important to understand that Pickler AI provides guidance and suggestions based on available data and common LCA modeling practices. The final responsibility for selecting and validating the material mapping always remains with the user.
Pickler is not an independent LCA consultancy or verification body and does not validate whether a specific mapping choice is scientifically “correct” for your exact product or use case.

Step 2: Identify the material or ask your supplier what the material actually is
If there is no direct match in IDEMAT, the next step is to identify what the material is actually made of and choose the dataset that best represents it.
Commercial or supplier names are often created for sales, branding, or ERP systems, but they usually do not describe the actual environmental material profile needed for LCA modeling.
For example:
Commercial name | What it actually represents |
Sugarcane PE | bio-based polyethylene (PE) |
rPET tray | recycled PET |
Molded fiber tray | molded paper fiber |
Ask your supplier
If you are unsure, the best next step is often very simple: ask your supplier what type of material it actually is.
Your supplier can often directly tell you:
the material family;
whether it is recycled or virgin;
whether it is bio-based or fossil-based;
whether coatings or laminates are involved;
and sometimes even which production process is used.
Useful documents include:
technical datasheets;
EPDs;
LCA reports;
or composition breakdowns.
Once those characteristics are clear, it becomes much easier to find a representative IDEMAT dataset or proxy.
Step 3: Find the closest representative IDEMAT dataset or proxy
Once you understand what the material is actually made of, the next step is to find the IDEMAT dataset that best represents it.
In many cases, there will not be a perfect 1-on-1 match. This is normal in professional LCA modeling.
Instead, the goal is to choose the dataset that best represents:
the material family;
recycled or virgin content;
bio-based or fossil origin;
production process;
and functional use.
For example:
Material | Recommended IDEMAT mapping |
rPET tray | recycled PET |
Sugarcane PE | bio-based PE |
Paper cup with PE coating | paper board + PE coating |
Bagasse tray | molded fiber or natural fiber proxy |
A good proxy is:
representative;
explainable;
realistic;
and consistent with similar products.
If multiple datasets seem possible, choose the one that most closely reflects how the material is actually produced and used in practice.
Troubleshoot: Can’t find a good match? Your material may need to be split first
Check whether the material should first be split into separate material lines.
For example:
Material | Weight |
PET 40% recycled | 100 g |
Recommended structure:
Material | Weight |
Recycled PET | 40 g |
Virgin PET | 60 g |
Why?
Because recycled PET and virgin PET should be mapped to different IDEMAT datasets.
The same logic applies to:
recycled vs virgin paper;
bio-based vs fossil plastics;
multilayer products;
coatings;
PCR vs virgin plastics.

Best practices
1. Use professional judgment, not perfectionism
No LCA model is perfect.
The goal of Fast-Track LCA is not to create an infinitely detailed scientific model for every possible product variation. The goal is to:
identify environmental hotspots;
compare alternatives consistently;
support better decisions;
and scale environmental insights across large product portfolios.
A good model is:
representative;
transparent;
explainable;
and scalable.
A common mistake in LCA modeling is trying to model every supplier-specific detail, coating, additive, or commercial variation separately, even when these differences have little impact on the final result.
In practice, environmental impact is usually driven by:
the main material types;
recycled vs virgin content;
production processes;
transport;
and total material weight.
That is exactly why representative secondary databases such as IDEMAT exist. The goal is not to perfectly recreate every supplier process, but to model products consistently using the best available representative datasets.
2: Don’t chase low-impact details
A common mistake in LCA modeling is spending too much time collecting highly detailed low-impact data, while overlooking the major environmental drivers of the product.
To keep models scalable and manageable, Pickler uses a 2% cutoff guideline.
Components below approximately 2% of the total product weight usually do not need separate modeling unless they significantly affect the impact.
This often applies to:
pigments;
inks;
trace additives;
very small coatings;
or minor processing aids.
The goal is to focus modeling effort on the data that creates the most decision-making value.
